Stop loss/margin call calculation help

[umarfxtrader]

Lets say I’m trading with 100k in my trading account.
I only want to place a buy order using 50% of my equity which would be 50k. I’m using 1:400 leverage on a fixed trading account.
I want to know how to calculate how many pips I would need to go down if making a buy/sell order until to get margin called. I want to know how to calculate the value per pip so I can set my stop loss so I will only loose 50k not my full account of 100k.

In short I want to know how to calculate my stop loss so I won’t loose more than 50k of my 100k In my account.

It's a completely backward way to trade - your stop-loss should be based on your trading strategy, not your account size, position size, or greed.

To answer your question, one variable is missing. It goes like this:
I want to know how to calculate my stop loss so I don't lose more than 50k of my 100k in my account with a position of X lots.

Why on earth would you risk 50% on a single trade?! 2 strikes and you're out. Horrible risk management.

2% is actually the industry standard however it is upto the traders how much they can afford to lose.
